Trends of area, production and productivity of foodgrain in the north eastern states of India
2013
Sharma, Amod
The present study was undertaken to study the trends of area, production and productivity of food grain in the northeastern states. The study was based on secondary data from 1980–81 to 2011–12. The data was collected from several government publications and web site. To analyze the trend of area, production and productivity of food grains in northeastern states, the linear, quadratic and exponential functional forms were used. To fit the trend, linear functional form was used due to its higher R² value as compared to other two forms. Besides these, compound growth rate, coefficient of variation and instability index was also estimated. The effects of area, productivity and their interaction towards increasing production were also estimated in the present study. The growing of food grain crops was not risky in the northeastern states as revealed by the lower coefficient of variation. The coefficients of variation (CV) of area, production and productivity of food grain crops were less than 0.551 percent. The instability indices for area, production and productivity for food grain crops in the northeastern states were positive and thereby indicating less risk for growing food grain crops in the region. The increase in production is due to increase in area as well as interaction of area and productivity of food grain crops in the states.
